Pull-out guide for drawers

Abstract

A pull-out guide for a drawer includes a carcass-side supporting runner and a drawer-side pull-out runner on each side of the drawer. A respective roller is supported on each runner. Running flanges of the pull-out runners cover running flanges of the supporting runners. The pull-out runners have horizontally projecting fins which are disposed below the running flanges of the pull-out runners and which have free ends projecting to below the running flanges of the corresponding supporting runners in such a way that the pull-out runners are secured against unintentional lifting off from the supporting runners.

We claim:  
     
       1. A pull-out guide fitting to be employed on a side of a drawer to guide movement of the drawer into and out of a body of an article of furniture, said fitting comprising: 
       a supporting runner to be mounted on the furniture body, said supporting runner including upper and lower running flanges and a running member;  
       a pull-out runner to be mounted on the drawer, said pull-out runner including a lower fixing flange to be connected to the drawer, a vertical flange extending upwardly from said lower fixing flange, an upper running flange extending from said vertical flange, at least one horizontal fin extending laterally from said vertical flange, and a running member;  
       said running member of said pull-out runner being guided between said upper and lower running flanges of said supporting runner, and said running member of said supporting runner running on said upper running flange of said pull-out runner;  
       said upper running flange of said pull-out runner extending above and covering said upper and lower running flanges of said supporting runner; and  
       said horizontal fin having a free end projecting below said upper running flange of said supporting runner, thereby preventing, upon an upward force being imparted to said pull-out runner, unintentional upward lifting away of said pull-out runner from said supporting runner.  
     
     
       2. A fitting as claimed in claim  1 , wherein said upper running flange of said pull-out runner has a longitudinal bead including laterally spaced side walls between which is guided said running member of said supporting runner. 
     
     
       3. A fitting as claimed in claim  1 , wherein said running members comprise rollers. 
     
     
       4. A fitting as claimed in claim  3 , further comprising a plastic block mounted on said supporting runner and having a stop projecting laterally at a level to be abutted from below by said fin, said roller of said supporting runner being mounted on said plastic block. 
     
     
       5. A fitting as claimed in claim  4 , wherein said roller of said supporting runner is mounted between side walls of said plastic block by a spindle mounted at opposite ends thereof in said side walls. 
     
     
       6. A fitting as claimed in claim  4 , wherein said plastic block has lateral guide surfaces to guide said pull-out runner. 
     
     
       7. A fitting as claimed in claim  4 , wherein said lower running flange of said supporting runner has projecting therefrom horizontal fin members, and said plastic block has projections fitting beneath respective said fin members, thereby mounting said plastic block on said supporting runner. 
     
     
       8. A fitting as claimed in claim  7 , wherein said plastic block is mounted on a front end of said supporting runner. 
     
     
       9. A fitting as claimed in claim  1 , wherein said upper running flange of said supporting runner has a free edge flange against which abuts said fin upon application of said upward force. 
     
     
       10. A fitting as claimed in claim  1 , further comprising separate front and rear retaining plates to mount front and rear ends, respectively, of said supporting runner to the furniture body. 
     
     
       11. A fitting as claimed in claim  10 , wherein said rear retaining plate has upper and lower retaining tabs receiving therebetween said rear end of said supporting runner, one of said tabs having a positioning structure providing lateral support of said rear end. 
     
     
       12. A fitting as claimed in claim  11 , wherein said positioning structure comprises two laterally spaced knobs projecting from said one tab, said rear end being positioned between said two knobs. 
     
     
       13. A fitting as claimed in claim  11 , wherein said positioning structure comprises a projection extending from said one tab into an open-ended slot in said rear end. 
     
     
       14. A fitting as claimed in claim  11 , wherein the other said tab has a hook fitting into a hole in said supporting runner. 
     
     
       15. A fitting as claimed in claim  11 , wherein the other said tab is resilient. 
     
     
       16. A fitting as claimed in claim  15 , wherein said other tab has a bend resiliently pressed toward said supporting runner.
